ROBA® servostop® Cobot: Spring-applied safety brake for lightweight robots

  • The hollow shaft brake for cobots
  • Suitable for smallest installation spaces
  • Low current consumption

The ROBA® servostop® Cobot is a safety brake that has been specially developed for the connection to hollow shafts with the largest possible internal diameter. It is ideally suited for integration into the smallest installation spaces such as the joints of lightweight robots or cobots, and can also be used at high ambient temperatures with extremely low energy consumption. The dynamic properties resulting from the unique design of the ROBA® servostop® Cobot are superior to those of spring-applied brakes with a classic design, especially in lightweight robots.
